T allwhom it may concern:

Be it known'that I, CHARLES J. IIOLUB, a citizen of the United States, residing at Newport, in the county of Campbell and have invented certain new and useful Improvements in Pipe- Formingh Iachines, of which the following is a specification.

This invention relates to machines for crimping the seams in uniting pipe sections and it deals more particularly with improve ments adapting such machines for successively joining a plurality of sections to form lengths of piping, such for example as that connnonly employed for carrying hot air from furnaces. 3

One objectwithin theconteinplation of this invention is to render'available "a simple I and inexpensive power press providing strumentalities for simultaneously crimping the entire periphery of the seam between sections of piping of a rectangular orother shaped cross-section. 7

Another object is to provide a mechanism of the foregoing nature in which the said instrumentalities may readily comprise in'-- terchangeable elements of various dimensions so that different sizesof pipe sections may be crimped as aforesaid."

Another object is to provide a mechanism as aforesaid such that piping considerable lengths and composed of a plurality of sections maywithout; diihculty be formed by successive operations;

Other objects will be inpart pointed out or indicated in the following description and in part renderedobvious bymeans of the annexed drawings. l To render this invention more completely comprehensible to those skilled in the art, drawings depicting one of the'many pos sible' embodiments thereof have been ap pended as a. part of thisdisclosurcand in such drawings like characters of reference parts throughout all 'Figure 1 is a front elevation" of press illustrative of this invention, showing a rec:

tangnlar centerform or core, together with" the top, bottom and side elements which function to simultaneously crimp four sides of the seam between the ipe}. sections:

Fig. .Zis a section takenthroughcline ofFig."l, showing" the Inountingiof center former cbre partlyfin section. and

partly in elevation. Fig. 3

typifies a seam between twosections of piping before being crimped into permanent form, and Fig. 4t indicates a. similar seam after being crimped in this machine.

Continuing now by way of a more'dc tailed descriptioinit may be noted preliminarily'that in order to enable the crimping surfaces of the dies to be formed as simply as possible, 2'. c. with plane faces, the preferred embodiment of this invention, as shown, is designed for use in connection with the form of scam indicated by Figs. 3 and 4i. 'At one end, the pipesection l is provided with an upturned flange 4 continuing into a downwardly turned shorter flange 5. The adjacentend of the companion pipe section 2 provided with an upturned straight flange 6, which is inserted in the groove formed by the flanges 4 and 5, the parts be ing proportioned and arranged very much as indicated by F ig. 3. By reason of-the tinplate of which the pipe sections may be formed, sufficient flexibility exists to permit of this interfitting the same, manually. It has been discovered that if some plane-faced pressure element be brought to bear against the apex ofthis seam, that by a straight-line depression, such seam will invariably turn into jthe. position indicated by Fig. at in which the section 2 is securely 'crimped to the, section 3. i 1

To effect this operation rapidly and perfectly, this invention proposes a'press arrangementsomewhat of the character shown in the drawings, in which A indicates a main frame in which is ournaled the shaft 7 of the driving niechanismywhich may, of

course, assume any desirable form. On this shaft is mounted a suitable eccentric, 8, which operates the pitman 9, which in turn through the adjustable connection 10, operates the plunger or stamp 11. On the underface of the latter is detachably affixed a die plate '12, which in. lengthcorrespondsy nvith the width of thepipe section to be crimped and constitutes a crimping die. 7

erably detachably affixed to similar memhere 17 which are supported on the table and which are arranged to move laterally in slides 18, being normally urged outwardly by springs 19', secured insuitable brackets.

T0 effect a translation of such slides, the

plunger is provided with cams '20,- which operateon the cam faces'21; By means of bolts 22, the cams 20, may be adjusted so as toproperly time the operations iofthe slides 21, so that all the crimpingdies may'simul- V ta'neously close in onthe four sides o fzthe pipe seams. By means of the adjustable I connection 10 ofthe plungert-he limit of 00- operative en a ement of all the dies relative l r 19 b to the core block and anvilis changed but by adjusting the cams 20 only'the limit of cooperative engagement of the side, dies is changed relative to eachother and to the core block.

The core or center piece is indicated by I 23 and preferably carries a sleeverl ike guide 24 upon'which the attendant may place the successive pipe; sections to insure that they:

may be held accurately in 'alinement' with the companion section during the crimping operation. This core 23 maybe provided with suitable means, such as the stem 25,"

whereby it maybe detachably mounted in the socket 26, wherebyit may be carried at the end of the elongated member 27 which v nip'ulation. I Hav1ng claim is preferably in the form of a tube to rem duce weight. The corei28 is I thus inter-1 changeable with other cores adapted for various shapes and dimensions of the pip-.

ing, The elongated support 27 is flexibly supported, as by a pivot at a point 28, provided by the standard 29, remote, from the crimping elements and the weight of the parts may be balanced by a suitable spring 30. By this arrangement, it is 'possibleto) crimp into a single substantially integral length of say tenfeet a plurality ofpipel lsections, 1, 2, 3, etc,

;It will thus be perceived that thislinvention is well. adapted to, achieve ftheobjects and ends above Stated and is characterized by great simplicity and convenience in madescribed my invention, I
